OceanObserver
Real-time ocean observing and processing
High performance acoustic and oceanographic data acquisition and processing for buoys, vehicles, and other platforms:
Up to 16 acoustic channels at up to 8–512 ksps
High-speed channel at 2048 ksps (optional)
Excellent noise floor, stable across sample rates and bands
On-board processing: detections/classifications, bearing estimates, and environmental measurements
Local and global data telemetry: Wi-Fi, VHF, Iridium, cellular, serial, Ethernet, or acoustic modem
Ideal solution for:
Marine mammal detection, identification, and localization
Multi-sensor ocean observing
Ambient and vessel noise quantification
Wind and tidal energy monitoring

Webinar: Observer and the Slocum glider
Watch the webinar to learn more about the OceanObserver, its use aboard the Slocum glider, and its successful mission to Canada’s Gulf of St. Lawrence in search of endangered North Atlantic right whales.
Customized processing & telemetry
On-board signal processing is done by PAMlab INT, the integrated version of JASCO’s PAMlab software suite: detection and identification of marine mammal calls and clicks, quantifying ambient noise and sounds from vessels and industrial noise sources, or customized processing.
For bandwidth-limited telemetry like cellular and Iridium, the OceanObserver converts the detection spectrograms into contours and ranks them by priority. The events are relayed via satellite and delivered by email.
Efficient modular design
The Observer was designed with modular components. The main board hosts your choice of daughterboards to suit your application. Unnecessary components are left out to minimize power consumption.
